Human CD3+ T cells are a type of white blood cell that plays a central role in the adaptive immune system. They are responsible for recognizing and responding to specific antigens, such as those from viruses, bacteria, and tumor cells. CD3+ T cells can be isolated from peripheral blood using either positive selection or negative selection.
CD3 is a surface protein that is expressed on all T cells. It is part of the T cell receptor (TCR) complex, which is responsible for recognizing antigens. CD3 also plays a role in T cell activation and signaling.
Positive selection involves using antibodies that bind to CD3 to capture T cells on a magnetic bead or column. The beads or column are then washed to remove any other cells, and the T cells are released.
Negative selection involves using antibodies that bind to non-T cells to capture them on a magnetic bead or column. The beads or column are then washed to remove the non-T cells, and the T cells are left behind.
Both positive selection and negative selection can be used to isolate high-purity CD3+ T cells. However, positive selection is generally faster and more efficient, while negative selection is less likely to activate the T cells.
Product Use Examples
Human CD3+ T cells are used in a variety of research and clinical applications, including: immunology research, cellular therapy and vaccine development.
Excellos 360 employs Excellos’s deep cell characterization approach to goes deeper than typical cell and donor screening to create a comprehensive immune cell profile for each donor, as well as an assessment of the metabolic and effector potential of their cells that looks beyond surface markers.
